Select timezone in web interface

[everanium]

Feature request:

It would be nice if you can temporary switch the timezone for graphs in WEB interface(not permanent setting for user). For example, I have a lot of servers that have a different timezone installed. If I look on the graph, I need manually calculate difference time (my computer timezone/server timezone). For example to detecting high load cron jobs.

It is convenient to watch charts in order to combine them in time right away with cron tasks.

Thank You.
